Do you hate it when wraiths brutally murder you NPCs? Do you like building houses in the sky only to have your dreams crushed by wyverns? Then keep reading. Spectral barrier the spectral barrier is an item with 1 sole purpose: to protect your NPCs from mobs that can pass through blocks (wraiths,wyverns,wandering eyes below 1/2 health ect) NOTE:this does NOT include bosses how it works is you place them around what you want to protect, placing one every 30 blocks or less. You can only see them when holding it and the spectral attuner. Could be placed on blocks like actuators. Crafting 5 souls of light @ Crystal ball (makes 4) Toolip: Protects you from wraiths and wyverns and such. Spectral attuner This handy little device makes everything work. Click a spectral barrier block with one ( they will have a yellow outline) and it will get a green outline. When all the ones you want have a green outline, right click the air to finishe the barrier. If you click one that is 31+ blocks away it will say: to far away, cannot link. Crafting 5 souls of light 2 iron/lead 1 ghostly anntena @ Crystall ball Ghostly anntena would have a 5% chance to drop from a wraith. When a blood moon rolls around the barrier weakens and can take 10 hits before having to recharge for 10 minutes. Well that wraps it up. Leave good feedback and suggestions in the comments. Goodbye! Note: this would take effect on wyverns as they are minibosses not full blow bosses to clarify that.
